Those of us in Parwich still using an old fashioned aerial have lost BBC 1. It went off early evening yesterday and at the time of writing this it was still off air. The BBC are aware of this and have someone working on the transmitter fault at present. They hope to rectify it soon. (Back on at about 4-30pm today.)
If you want to report any transmitter faults go to the UK Broadcast Transmission website for the contact details for each channel.

Hope it’s fixed in time for Strictly!
